A vibration welded article includes an outer member having a substantially V-shaped portion, and an inner member that is vibration welded to the outer member. The outer member includes a substantially plate-shaped base surface portion, and a slope portion formed obliquely relative to the base surface portion. The slope portion has an outer member opening which is opened to attach another component. The inner member includes a first joint surface portion that is vibration welded to the base surface portion, a second joint surface portion that is vibration welded to the slope portion, and at least one protruding portion that protrudes from the second joint surface portion toward the base surface portion.

A coupling may be configured to receive and secure an insertion end of a conduit. An outer surface of the insertion end of the conduit may be smooth and free of grooves, flanges and beads. A first member of the coupling may define a first passageway. A second member of the coupling may define a second passageway. The first member may be in engagement with the second member. A gripping ring having an inner edge defining a series of teeth may be disposed within the second member. A support ring and O-ring may also be disposed within the second member.

A valve arrangement for dispensing a fluid is proposed. The valve arrangement comprises a valve plate for fixing the valve arrangement to a container, a valve housing and a fixing part for fixing the valve housing to the valve plate. The fixing part is welded with the valve plate. Furthermore, a dispensing apparatus with a container and a valve arrangement as well as a production method are proposed.

An aerosol container suitable for use as an aerosol dispenser. The aerosol container includes at least a valve and product delivery device joined to an outer container. The valve and product delivery device have respective annular welds or other seals joining the valve and product delivery to the outer container. The welds, or other seals may be concentric, with one circumscribing the other, in the same plane or different planes. Suitable product delivery devices include bags and dip tubes.

The invention relates to a connection element, in particular a thermal adhesive bonding boss, to be introduced into at least one component, in particular a hollow chamber component, in particular a plate-shaped hollow chamber component which has hollow chambers, under the effect of pressure and rotation, comprising a main part which comprises a thermoplastic synthetic material. The connection element has a longitudinal axis and is designed to rotate about the longitudinal axis, and the connection element has an upper face with a tool placement point and a lower face which faces away from the upper face, wherein the connection element has an expanding portion made of a thermally activatable expandable material on the main part on a circumferential surface extending between the upper face and the lower face.

An aerosol container suitable for use as an aerosol dispenser. The aerosol container includes at least a valve and product delivery device joined to an outer container. The valve and product delivery device have respective annular welds or other seals joining the valve and product delivery to the outer container. The welds, or other seals may be concentric, with one circumscribing the other, in the same plane or different planes. Suitable product delivery devices include bags and dip tubes.

A method of anchoring a connector in a first object is provided, wherein the connector includes thermoplastic material in a solid state. The method includes bringing the connector into physical contact with the first object, rotating the connector relative to the first object around a proximodistal rotation axis and exerting a relative force by the connector onto the first object, until a flow portion of the thermoplastic material of the connector becomes flowable and flows relative to the first object, and stopping rotation of the connector, whereby the flow portion anchors the connector relative to the first object, wherein a distal end of the connector is equipped for cutting/punching into the first object and/or for removing material therefrom.

A biodegradable container including a unitary polymeric body element having a top portion and a cylindrical body portion. The top portion has a cylindrical neck wherein the cylindrical neck defines an inner surface and an outer surface. The container further includes a polymeric bottom element welded to the cylindrical body portion of the unitary polymeric body element. A polymeric cap defines an internal rim configured to be received by the inner surface of the cylindrical neck. The polymeric cap includes an external cover having an interior surface which may be tapered so that the outer surface of the cylindrical neck and the interior surface of the external cover form an inner seal. The interior surface of the external cover may also form an outer seal with the outer surface of the cylindrical neck when the polymeric cap is in a closed position.

The relates to a method of mechanically securing a first object to a second object and includes the steps of: providing the first object including thermoplastic material in a solid state, providing the second object with a generally flat sheet portion having an edge, positioning the first object relative to the second object and bringing the first object and the second object to a relative movement to each other. The relative movement includes a rotational movement, such that a melting zone including flowable thermoplastic material is formed and such that thermoplastic material of the melting zone flows around the edge to at least partially embed the edge in the thermoplastic material. The invention further concerns a connector that is suitable for being used in a method according to the invention.

A method of forming a weld joint is provided. A first component having a base portion and a flange extending from the base portion is provided. A second component is provided. The second component and the flange are brought into abutment and a load is applied to the flange via the second component. The flange is biased against the second component by a reaction of the first component to the load. One of the first and the second components is vibrated to form a weld joint between at least a part of the second component and at least a part of the flange.
